ABSTRACT
Objectives To study the clinical effects of percutaneous kyphoplasty on senile osteoporotic vertebral body compression fractures.Methods The 87 elderly patients with osteoporotic vertebral body compression fractures were randomly grouped into control group (n=42) treated with percutaneous vertebroplasty and observation group (n=45) treated with percutaneous kyphoplasty in our hospital from June 2013-March 2016.And the clinical curative effect before and after treatment was compared and analyzed.Results The visual analog scale (VAS) pain score in observation group versus control group was (8.49±2.86) vs.(8.56±2.98),(t=0.11,P>0.05) before treatment,and[(2.58±1.34) vs.(3.34±2.01),t=2.09,P< 0.05],[(2.06±0.97) vs (3.87±1.96),t=5.51,P<0.05]and[(1.09±0.89) vs (2.37±1.29)],t=5.42,P<0.05]at 1 week,4 weeks,and 12 weeks after treatment respectively,showing statistically significant improvement after treatment.The data of kyphosis angle by using Cobb angle,Oswestry lumbar dysfunction index (ODI),mean time of postoperative ambulation,and mean postoperative hospital stay were similar to that of the visual analog scale (VAS) pain score,showing statistically significant improvement after treatment (all P<0.05).The incidence[cases (%)]of bone cement leakage was lower in observation group[3(6.7)]than in control[9(21.4)](χ2=3.98,P<0.05).Conclusions Clinical treatment effects of percutaneous kyphoplasty on the elderly patients with osteoporotic vertebral body compression fractures are superior to that of percutaneous vertebroplasty.Percutaneous kyphoplasty can effectively relieve pain,and improve body function disorders and the quality of life.
ABSTRACT
Objective To investigate the difference in the pass rate of intensity?modulated radiation therapy ( IMRT) planning in patients with different tumors and its value in determining pass rate thresholds. Methods A total of 35 verified IMRT plans for each of esophageal cancer, nasopharyngeal carcinoma, breast cancer, cervical cancer, and lung cancer were selected consecutively, and a one?way analysis of variance was used to investigate the difference in pass rate. A single pass rate threshold was used to test all IMRT plans, and the pass rate thresholds of IMRT plans for different tumors were calculated based on normal distribution law. Results There was a significant difference in the means between the 5 groups of data ( F=35. 83, P<0. 01) , and there was also a significant difference between any two groups ( P=0. 000) . There were statistically significant differences between nasopharyngeal carcinoma group and other four groups ( P=0. 000) . The difference was not only significant between the breast cancer group and the esophageal cancer group ( P=0. 001) , but also between the breast cancer group and the lung cancer group ( P=0. 033) . The calculated results of each threshold were 93. 37%, 89. 34%, 97. 68%, 95. 99%, and 95. 42%, respectively. Conclusions Different thresholds should be used for IMRT plans for different tumors, and the normal distribution law can be used to calculate the threshold.
ABSTRACT
Objective To explore the reasonable clinical target volumes by analyzing the characteristic of mediastinal lymph node metastases in non-small-cell lung cacer (NSCLC).Methods 291 NSCLC patients was performed pre-therapy CT scans,and the incidence of mediastinal lymph node metastases was analysed.Results Among the 152 patients with right lung NSCLC,the incidence of involvement of the ipsilateral supraclavicular lymph nodes was 15.8 ％ (24/152),and the incidence of involvement of the contralateral lymph nodes was 6.6 ％ (10/152).The highest incidence of mediastinal nodal involvement occurred in the ipsilateral hilar nodes (59.2 ％),followed by area 4R (56.6 ％),area 1-2R (36.2 ％),area 7 (33.6 ％),area 4L(20.4 ％),area 10-11L (5.9 ％),area 6 (3.9 ％),area 5 (2.0 ％),area 1-2L (2.0 ％),respectively.Among the 139 patients left lung NSCLC,the incidence of involvement of the ipsilateral supraclavicular lymph nodes was 15.8 ％ (23/139),and the incidence of involvement of the contralateral lymph nodes was 5.8 ％ (8/139).The highest incidence of mediastinal nodal involvement occurred also in the ipsilateral hilar nodes (54.0 ％),followed by area 7 (33.8 ％),area 4R (26.6 ％),area 4L (24.5 ％),area 1-2R (15.8 ％),area 5 (10.8 ％),area 6 (9.4 ％),area 1-2L (5.8 ％),area 10-11R (5.0 ％) respectively.Conclusion The right side primaries or left side primaries of NSCLC have different high risk lymph node areas for metastasis,and selective irradiation to these lymph node areas maybe increase the tumor control rate and reduce the recurrence rate.
ABSTRACT
OBJECTIVE:To investigate the effect of evaluation method on management of prescription. METHODS:A total of 24 000 prescriptions of 12 months were evaluated with both method 1 devised by our hospital and method 2 specified in ordinance of Management of prescription. The administration department intervened physicians’ prescription behaviors according to the evaluation results. The change of data in method 1 was compared with that in method 2. RESULTS: In method 1,the problems of usage and dosage increased a little while other irrational problems lessened largely. In method 2,the average amount of drug categories reduced a little while the other data increased a little. CONCLUSION: The effect of evaluation and intervention in method 1 are superior to those in method 2.
